I IMPROVEMENT IN PRIMING- CARTRIDGES.

' Specificationformtng part of Letters Patent No. 53,501, dated March27, 1866.

To all whom it may concern Be it known that 1, THOMAS L. STURTE- VANT,of Boston, in the county of Suffolk and State of Massachusetts, havemade a new and useful improvement or invention having reference toCartridges or Chargers for Breech- Loading Fire-Arms and do herebydeclare the same to be fullydescribed in the following specification andrepresented in the accompanying' drawing, which is a longitudinalsection of a cartridge or charger provided with my 'invention.

In this cartridge the percussion-cap (shown at O in the drawing) is tobe placed inverted in the powder or charge chamber 0, and may rest in acavity or on a seat, f, made in or on the breech B. It is to be explodedby means ofrthe blow of the hammer of the lock of the fire-arm directedupon a plunger, D,passing down laterally into the cartridge, and thronga hole, 9, made in its upper part.

It is notnew to have a percussion-cap so placed within a cartridge; noris it new to explode it by such means. It has been customplied to theplunger, and with it is inserted in the cartridge, the plunger beingconstructed not only with a carrier, at, to fit into the cap 0, but witha cap-entrance stopper, 12, having a diameter at least equal to that ofthe cap, and designed to fill or stop the entrance-hole 9, made in thetop of the case of the charger.

The part c of the plunger which projects above the stopper 1), I form ofadiameter less than the stopper, in order that there may be a shoulder,h, at the top of the stopper to rest against the bore of the gun orfire-arm when the cartridge may be within the said bore. This shoulderoperates to prevent the pressure or explosion of the charge from forcingup the hammer and throwing the plunger out of the barrel.

I claim 1. A percussion-cap plunger or discharger as made with acap-entrance stopper, 1), and with a cap-carrier, 01,, arranged anddesigned to operate therewith, as and for the purposes set forth.

2. The combination of the shoulder h, arranged at the top of thestopper, with the said stopper b, applied to the cap-discharger, for thepurpose set forth.

T. L. STURTEVANT.
